My toilet needed a new handle and flapper mechanism. Also, the shut off valve leaked. The parts for these fixers are inexpensive. I estimate about 30 minutes of work. Yet they asked over $600 for the repairs. This was too expensive. I paid the "visit fee" and asked them to leave. The only positives were the quick and courteous response to my call.

No one enjoys spending money on a new water heater. It never goes out at a convenient time. We were happy we chose Mike Williams Plumbing. From our first contact, we were given a time line. An appt was made. Josh & Kendall did a good job of explaining the issue. They also gave us a choice of repair or new with pricing for both. Explanations were concise & clear.

We chose to go with new as our water heater was already 11 years old. It had to fit in a very limited space. They made sure it did & fit it in perfectly. They left the space cleaner than when they arrived. Professional & pleasant throughout. Thank you gentlemen for a job well done.

Great Service! Very fast and responsive! We have a few rental properties in the area so repairs are always a bit tricky when scheduling, especially living out of state. Our tech was George and he was such a pleasure to speak with on the phone. Job was done quickly and tenants spoke highly of him! Mike Williams Plumbing, Heating and Air will definitely be my go to plumber for the Decatur Area! Thank you!

Do not use this company. They scam older folks by overcharging and advising that HVAC units need replaced even if they're working fine. My brother is 72 and handicapped. He called MW to do a basic cleaning of his HVAC unit. They came out an gave him an estimate of $750 to clean the furnace! They guy said since it cost so much my brother might as well replace it instead!

It was only 10 yrs old! Thankfully he asked me before paying or replacing it! I have since learned from the owner of another HVAC service company that has hired former MW techs that MW gives their techs scripts to use to scam older folks! DO NOT USE MW AND WARN OLDER FOLKS TO STAY AWAY FROM THEM!

Guy was at my house for like 10 minutes. Charged $99 for the visit. Then he told me I needed a fan motor and quoted me $1200. I found the motor for $150 and another company charged me $75 to install. People at Mike William's were nice but they charge double what others charge.

We had them replace our water heater, which was fine as far as I know. We also signed a maintenance contract with them. When they came out to do their "check, " they completely ignored the water heater and after examining the furnace for maybe a few seconds, told us we needed a new furnace. The cost estimate given to us was in excess of $11,000. Our furnace/ac unit is only 15 years old, so we contacted the company that installed it.

The ONLY reason we didn't have them do the water heater is because they don't do water heaters. Lo and behold, we did not need a new furnace, what we needed was a $500 part for the BACKUP UNIT. There was NOTHING wrong with our furnace. Do NOT let these people into your home, do NOT sign a maintenance contract and, most important, if they tell you something or something needs to be replaced, get a SECOND OPINION.

Had an issue last year, Became a member of the monthly service program, then I got sick. Mike Williams company called me and told me I needed an A/C and furnace inspection. Had the inspection and had them Replace the A/C, the worker was great. Called them back for sewer issues. waited 3 weeks, they kept canceling the appointment, called to cancel the monthly program and was told it will void their warranty for my BRAND NEW A/C!

What a racket! Will not recommend them to anyone and I've been told by several people at my church that Mike Williams is not a good company. Called Rick Ray about my sewer issue and they showed up the NEXT day!

Greg Johnston arrived on time. Greg is very thorough and efficient on site and very respectful, patient, and helpful while training new staff Billy. Greg is very detail oriented and I'm sure he will pass that on to Billy. Great job to both technicians and I'm now ready for warmer weather. Service: A/C system maintenance

The problem had been identified. Greg went the extra mile to repair it to prevent another incident. Also was able to give me a lower price when I rejoined their service plan. Would definitely recommend! Services: Plumbing leak detection, Heating system repair

Called, made an appointment, ask them if they had the equipment to reach 115 foot, was told everything they needed would be on the truck. Service technician arrived on time. Informed us they don't carry equipment that long and charged us $79 for nothing. Called the company and was told they were sorry and would not cash the check. Guess what, they cashed it! Will never recommend or use again.

In the two months since Mike Williams installed my systems, they have now returned FIVE TIMES to fix constant issues. I had two split systems installed, a furnace, a new AC unit, and a hot water heater. Nothing but constant issues so far. Making matters worse, on the last "Fix" which didn't fix the issue, the technician was working outside with an outdoor breaker box.

It wasn't until a day after they left that I realized they didn't put the cover back on the box. Had it rained outside, there was a very good chance of an electrical fire or a destroyed (and expensive) breaker box. The issues I've had still haven't been resolved and the last technician literally asked me if I knew where certain components were located (The PCB Boards on my dual split-system). Ummm. that's not my job, that's their job.

On top of it, there is a water stain on one of my ceilings from an improperly installed line that was causing condensation build-up. Absolutely NOTHING but issues. The one shining light has been the technician Clint who has been super professional when being sent out to re-evaluate stuff that has gone wrong and to fix some of the issues and troubleshoot everything.

This place is a joke. I used them and wrote them off shortly after. My son is a new homeowner and only chose them because they were the only place that could come out "today". Once he talked to me he realized his mistake. He called the guy who left for the part. Even though he, himself, had already diagnosed the problem. They still charged him a $250 restocking fee on a $105 part. Total BS. They pull you in with their half price service call and then change you double for everything else.

I felt the entire visit was a selling frenzy trying to get me to buy a "special". One special was for $250 and I said no. Then he dropped down to a litany of $99 specials. Looking for a new plumbing firm that I feel I can perhaps trust.

Service man that came out was rude, mocking. Treated me like I was dumb, very unprofessional and I will never use them again or recommend them to anyone, save your time and money

Horrible, pretend customer service but that doesn't make their lack of professionalism any better when your furnace doesn't work!

This is possibly the worst experience I've had in years. I wouldn't recommend these people to my worst enemy. That's how bad and a rip off they are. I could spend hours going on and on about why. U and I don't have that kind of time because the list is that long. I'm not a person who gives up easily, I like to try and see the best in all thing. But Mike Williams has got me stumped. Please do urself a favor. Move on

Will never use again, called them out for a sump pump replacement and got well and truly overcharged. I understand there is a call out charge for weekends but the almost a $1000 to replace a sump pump? Find someone else folks, and stay away from these rip off merchants.

Beware of this company's quoting system. They had the nerve to sell me a quote for 69.95. We were not in an emergency and we called to have a Drop standard 22" by 33" kitchen sink. We are talking about a standard kitchen sink. That needs nothing special than stand install equipment. We already purchase the sink from Lewis and ordered nice garbage disposal.

So we may need PVC replacement pipes which should cost no more than 50.00 with a plumber Equipment uplift fee. A QUICK GOOGLE SEARCH FOR GENERAL PRICING ON A INSTALL. Will give you a general cost with a break down of why. The cost should be anywhere from 250 to 700 on the high end due to a special reason. And that would be for special cutting or fitting.

Will can you guess there quote. Will it was over 2000.00 for them to install a sink I already owned, garbage disposal I already purchased. Then they offered me a monthly maintenance plan I can save a percentage now if I take it to 6 months. Bringing the quote down to 17xx.00. What a joke.then he offered to take payments. I should them the door, what a joke.

There quote had no breakdown if pricing. I have the quite and I might upload as proof of this unbelievable bold company. Sorry but this scam may work for some possibly elderly which makes me feel sick. Google your quote. I saw other people quote that they were overcharged. But with no break down at made me sick to pay for that quote. 70.00 down the drain

Ripoff artists! Sold my property 6 months ago. Informed them every month to stop the monthly fee which went up without notice as well! Keep telling me that can't due to the Patriot Act! Liars. Over chargers and frauds!

Don't sign up for the monthly plan. You call to cancel and they say they will but a month or two later you see that they didn't. When you call they tell you that you need to send a letter. Would have been nice to know when I called the first time.

Unreliable. Monthly fee charged but can't be trusted to show up for appointments. Canceled twice after waiting 6 hours for tech. Finally tech came for six month maintenance check and less than a week later the a/c unit isn't working without any notice service concerns on a 6 year old unit. Called 3 times last night for emergency service and was promised a tech would call shortly. Didn't receive a response until 7:30 the following morning. Exterior temperature 95 degrees, interior 84 and they still can't tell me if they can make an appointment today. A complete waste of money.

I called for service and the tech showed up and told me I had problems that I didn't have and then gave the flimsy excuse that they didn't do work on mobile homes.

Used coupon for furnace check and cleaning ($80). Replaced blower capacitor for $300 ($10 part that takes literally 5 minutes to replace). Induced my wife to sign a service contract $(100). Felt service was very over priced. Technician covered furnace with decals and intentionally covered up names of other companies that serviced the unit. You are probably better off using another company. Get a recommendation from a friend.

I scheduled routine maintenance on our heating system. I rarely have a day off during the week so I scheduled an appointment for one particular day that I did have off. I waited around all day to find out that they were too busy to keep my appointment. So even though I had an appointment, they couldn't keep their end of the bargain and actually come out after I waited around at home all day for them to come. Very disappointed in this customer service!

Called this company to get a dishwasher installed. The installer quoted me over $900 to install it because he had to go through one cabinet in order to reconnect the hoses on the new dishwasher. After the discount they company supposedly offers after you agree to the monthly maintenance service I still ended up paying over $750 for a service that took no more than an hour.

After it was all said and done, the installer used ONE single screw to keep the dishwasher in place instead of the two that came with the dishwasher and were needed. A month later, that one screw came out and now the dishwasher comes out of place every time the door is open and needs to be pushed in after loading. WILL NEVER USE THIS COMPANY AGAIN FOR ANYTHING!
